Tasks

Improving performance


This category is designed to help you achieve and maintain the best possible performance for your CICS system. The emphasis is on improving performance, and provides information about the best ways to achieve such performance.

Sections within this category can help you monitor and assess performance by understanding the balance between system availability, response times, and resources

Performance considerations are discussed from the installation of a new system, through to gathering data to establish performance objectives. Several basic steps explaining how to tune a system are included, with guidance on deciding on measurement criteria. The aim is to help you recognise what is practically measurable, and what is a realistic workload within the confines of your budget.

Details of performance analysis give help in producing a measurement and evaluation plan, and especially useful is a topic on identifying CICS constraints. A comprehensive section on collecting and understanding CICS statistics is also available.
